Abstract

The outer side (33) of a sealing-bush (3) touches the inner side of the pipe. An elongated element (2) which has a longitudinally conical outer surface (21) with a wider end (24) leads through the sealing-bush. The wider end o f the conical element has a flange (25) possessing a slightly smaller diameter tan the inner diameter of the pipe being sealed. Between the flange and the sealing bush is a cutting ring (4) which has a cylindrical outer side(41) and a truncated cone-shaped inner side (42)conically widening towards the flange. The ring has a thin-walled (43) and an opposite facing thick-walled (44) end
